Hi, I installed snow via R.app (from R 2.6.0) on OS X (10.4.11, Tiger), though I did not install Rmpi or Rsprng. My first question - has anybody installed Rsprng on OS X? The link from the CRAN package page seems to indicate that the sprng code was not installed rather than Rsprng not building. Second, I tried to create a cluster using the SOCKET option by doing cl <- makeSOCKcluster(rep('localhost',2)) However, after issuing this, R just seems to hang. I have set up passwordless ssh, so that doing ssh localhost logs me into my machine without any password, so I'm not sure what the problem is Any pointers would be appreciated ------------------------------------------------------------------- Rajarshi Guha <rguha at indiana.edu> GPG Fingerprint: 0CCA 8EE2 2EEB 25E2 AB04 06F7 1BB9 E634 9B87 56EE ------------------------------------------------------------------- ...but there was no one in it....... - RG
